Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically to a pickling solution circulation filtration and recovery device for metal sheet processing. Background Technology

[0002] Metal sheet processing is a process of shaping metal sheets by cutting, bending, stamping, etc. During the metal sheet processing, pickling solution filtration and recovery devices are required to purify pickling waste liquid and recover useful components.

[0003] Traditional filtration devices lack pretreatment capabilities and cannot pre-separate metal debris mixed in pickling solutions using magnetic attraction. These metal debris directly enter the filtration system with the pickling solution, increasing the load on subsequent filtration components, leading to a significant decrease in filtration efficiency and an increase in the frequency of filter clogging.

[0004] To address the above technical issues, we have designed a circulating filtration and recovery device for pickling solutions used in metal sheet processing. Utility Model Content

[0005] The purpose of this invention is to provide a pickling solution circulation filtration and recovery device for metal sheet processing, which has the advantage of pre-separating metal debris mixed in the pickling solution through magnetic attraction. This solves the problem that existing pickling solution recovery filtration devices cannot pre-separate metal debris mixed in the pickling solution through magnetic attraction during use, which causes metal debris to directly enter the filtration system with the pickling solution and easily clog the filter components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating filtration and recovery device for pickling solution in metal sheet processing, comprising a housing, a feed pipe fixedly connected to the left side of the top of the housing, support plates bolted to the left side of the front side and the left side of the rear side of the feed pipe, a hydraulic rod bolted to the right side of the support plate, a movable plate bolted to the output end of the hydraulic rod, a rectangular plate riveted to the opposite side of the movable plate, a magnetic rod bolted to the left side of the rectangular plate, a scraper bolted to the right side of the inner cavity of the feed pipe, the left end of the magnetic rod passing through the feed pipe and the scraper in sequence, an L-shaped plate riveted to the bottom of the inner cavity of the housing, a slide rail bolted to the top of the L-shaped plate and the top of the inner cavity of the housing, a filter plate bolted to the inner cavity of the slide rail, a fan bolted to the right side of the top of the housing, a telescopic pipe connected to the outlet of the fan, and a purging mechanism bolted to the front of the housing.

[0007] Preferably, the purging mechanism includes a drive motor, the rear side of which is connected to the housing by bolts, the output end of which extends through the inner cavity of the housing and is connected to a distribution pipe by bolts, the rear side of which is movably connected to the inner wall of the housing by a bearing, a nozzle is connected to the left side of the distribution pipe, the nozzle is located on the right side of the filter plate, and the bottom end of the telescopic pipe extends through the inner cavity of the housing and is connected to the distribution pipe.

[0008] Preferably, a guide plate is bolted to the left side of the bottom of the inner cavity of the box, and the right side of the guide plate is in contact with the L-shaped plate.

[0009] Preferably, a drain valve is connected to the left side of the bottom of the box, and a drain valve is connected to the bottom of the right side of the box.

[0010] Preferably, the number of magnetic rods is several, and the magnetic rods are arranged alternately.

[0011] Preferably, a sealing plate is bolted to the top of the front side of the housing, and the sealing plate is located in front of the filter plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model has a pre-treatment function of magnetic attraction through the cooperation of a support plate, hydraulic rod, movable plate, rectangular plate, magnetic rod and scraper. When the pickling solution enters through the feed pipe, the magnetic rod can quickly adsorb the metal debris in it. After the pickling solution is treated, the hydraulic rod drives the movable plate to move the magnetic rod, and the scraper can scrape off the metal debris adsorbed on the surface of the magnetic rod.

[0013] 2. This utility model has the advantage of self-cleaning function through the cooperation of telescopic tube and purging mechanism. The fan supplies air to the distribution pipe through the telescopic tube, and the drive motor drives the distribution pipe and nozzle to rotate. The nozzle 143 purifies the filter plate in all directions to avoid filter plate clogging, thereby effectively improving filtration efficiency and device service life. Attached Figure Description

Detailed Implementation

[0016] Please see Figures 1-6 A pickling solution circulation filtration and recovery device for metal sheet processing includes a housing 1. A feed pipe 2 is fixedly connected to the left side of the top of the housing 1. The feed pipe 2 serves as a channel for the pickling solution to enter the device, guiding it precisely into the housing 1 and preventing spillage. It also provides a stable flow environment for pre-treatment with magnetic attraction. Support plates 3 are bolted to the left side of the front side and the left side of the rear side of the feed pipe 2. A hydraulic rod 4 is bolted to the right side of the support plate 3. A movable plate 5 is bolted to the output end of the hydraulic rod 4. A rectangular plate 6 is riveted to the opposite side of the movable plate 5. The rectangular plate 6 is used to fix and install magnetic rods 7, allowing multiple magnetic rods 7 to be arranged in an orderly manner, ensuring a reasonable spacing between them and improving the removal of metal particles from the pickling solution. The adsorption coverage surface for debris is as follows: a magnetic rod 7 is bolted to the left side of the rectangular plate 6, and a scraper 8 is bolted to the right side of the inner cavity of the feed pipe 2. By setting the scraper 8, when the magnetic rod 7 moves, it can closely adhere to the surface of the magnetic rod 7 and scrape off the adsorbed metal debris, realizing the self-cleaning of the magnetic rod 7 and ensuring the continuous and stable adsorption performance of the magnetic rod 7. The left end of the magnetic rod 7 passes through the feed pipe 2 and the scraper 8 in sequence. An L-shaped plate 9 is riveted to the bottom of the inner cavity of the box 1. The top of the L-shaped plate 9 and the top of the inner cavity of the box 1 are both bolted to the slide rail 10. The inner cavity of the slide rail 10 is bolted to the filter plate 11. A fan 12 is bolted to the right side of the top of the box 1. The air outlet of the fan 12 is connected to the telescopic pipe 13. A blowing mechanism 14 is bolted to the front side of the box 1.

[0017] Please see Figure 1 and Figure 3 The purging mechanism 14 includes a drive motor 141. By setting the drive motor 141, the distribution pipe 142 and the nozzle 143 can be rotated to achieve all-round purging. The rear side of the drive motor 141 is connected to the housing 1 by bolts. The output end of the drive motor 141 passes through the inner cavity of the housing 1 and is connected to the distribution pipe 142 by bolts. The rear side of the distribution pipe 142 is movably connected to the inner wall of the housing 1 by bearings. The left side of the distribution pipe 142 is connected to the nozzle 143. By setting the nozzle 143, the nozzle 143 can concentrate the airflow and accurately act on the surface of the filter plate 11 to efficiently clean impurities. The nozzle 143 is located on the right side of the filter plate 11. The bottom end of the telescopic pipe 13 passes through the inner cavity of the housing 1 and is connected to the distribution pipe 142.

[0018] Please see Figure 1 A guide plate 15 is bolted to the left side of the bottom of the inner cavity of the box 1. By setting the guide plate 15, the scraped metal debris and sediment impurities can be guided to converge towards the drain valve 16 for easy centralized discharge. The right side of the guide plate 15 is in contact with the L-shaped plate 9.

[0019] Please see Figure 1 A drain valve 16 is connected to the left side of the bottom of the box 1. By setting the drain valve 16, the accumulated metal shavings and impurities can be discharged periodically. A drain valve 17 is connected to the bottom of the right side of the box 1.

[0020] Please see Figure 4 There are several magnetic rods 7, which are arranged alternately.

[0021] Please see Figure 2 A sealing plate 18 is bolted to the top of the front side of the housing 1. The sealing plate 18 facilitates the user to disassemble and replace the filter plate 11. The sealing plate 18 is located on the front side of the filter plate 11.

[0022] In use, connect the device to an external power supply and controller. Continuously inject the pickling solution to be treated into the tank 1 through the feed pipe 2. As the pickling solution flows through the feed pipe 2, the magnetic rod 7 uses strong magnetic attraction to quickly capture metal debris mixed in the pickling solution, achieving pre-separation of the metal debris from the pickling solution. The pre-purified pickling solution continues to flow into the tank 1. After overflowing from the tank 1, the pickling solution passes through the filter plate 11. The filter plate 11 performs secondary filtration on fine impurities and non-metallic particles in the pickling solution, further improving its purity. The purified pickling solution collects at the bottom right side of the tank 1, while larger impurities settle at the bottom left side of the tank 1's inner cavity. After the pickling solution filtration is complete, first open the drain valve 16. The sediment generated at the bottom of the tank 1 due to filtration is guided by the guide plate 15 and discharged through the drain valve 16 to the outside of the device. After the sediment is discharged, temporarily keep the drain valve 16 open. In the start state, the hydraulic rod 4 is activated via the external controller. The hydraulic rod 4 drives the movable plate 5, rectangular plate 6, and magnetic rod 7 to move to the right. During the movement of the magnetic rod 7, the metal debris adsorbed on the surface is completely scraped off by the scraper 8. The scraped metal debris slides down along the guide plate 15 and is discharged to the outside of the device through the opened drain valve 16. After filtration, the external controller starts the fan 12 and drive motor 141. The airflow generated by the fan 12 is delivered to the distribution pipe 142 through the telescopic pipe 13. The drive motor 141 drives the distribution pipe 142 and the nozzle 143 to rotate. The nozzle 143 sprays the airflow directionally onto the surface of the filter plate 11, sweeping the filter holes and the impurities attached to the surface in all directions. The impurities generated by the sweeping are guided by the guide plate 15 and collected to the bottom left side of the box 1. At this time, the drain valve 16 can be opened again to discharge the impurities. After cleaning is completed, the fan 12, drive motor 141, and drain valve 16 are turned off.

[0023] In summary, this pickling solution circulation filtration and recovery device for metal sheet processing, through the cooperation of support plate 3, hydraulic rod 4, movable plate 5, rectangular plate 6, magnetic rod 7 and scraper 8, solves the problem that existing pickling solution recovery filtration devices cannot pre-separate metal debris mixed in the pickling solution through magnetic attraction during use, which leads to metal debris directly entering the filtration system with the pickling solution and easily clogging the filter components.
